1993 buick rivera has not been started or moved in 3 years. It has been sitting in driveway. what should i expect?

Battery will probably be dead, recharge or replace it, Gas is probably stale, will have to drain out old gas and replace with fresh. Be sure to check engine oil level, coolant level, power steering level and top off if needed. You might be lucky and it will start on the stale gas, give it a try first, if not then you will need fresh gas. Hope this helps

Dead battery and bad gas,should start but will have bad gas smell, after you got it running add gas and fuel additive, change all fluid, check belt's and hoses. also have brakes checked.Hope this was helpful.
